Abstract

According to one embodiment of the present invention, there is provided a method of analyzing a computer infrastructure providing a service, an intended quality level of the service being defined by at least one service level objective defining a service level quality objective and a related compliance level, the computer infrastructure comprising a plurality of components, the method comprising: obtaining first service level objective compliance data for a selected service level objective, the compliance data being calculated using data collected from the computer infrastructure; calculating second service level objective compliance data for the selected service level objective using in part the collected data and for a selected service level quality objective a value that meets that objective; calculating a difference between the first and second data; and identifying, based on the calculated difference, one or more components suitable for modification.

Claims

1. A method of analysing a computer infrastructure providing a service, an intended quality level of the service being defined by at least one service level objective defining a service level quality objective and a related compliance level, the computer infrastructure comprising a plurality of components, the method comprising:

using a processor-based system to obtain first service level objective compliance data for a selected service level objective, the compliance data being calculated using data collected from the computer infrastructure;

using the processor-based system to calculate second service level objective compliance data for the selected service level objective using in part the collected data and for a selected service level quality objective a value that meets that objective;

calculating a difference between the first and second data; and

identifying, based on the calculated difference, one or more components suitable for modification.

2. The method of claim 1, further comprising, where the quality level of the service is defined by a plurality of service level objectives, repeating using the processor-based system to calculate second service level objective data for each service level quality objective of each service level objective.

3. The method of claim 1, wherein the step of identifying further comprises, where the calculated difference is within first predetermined limits identifying a component for modification in a first manner, and where the calculated difference is within second predetermined limits identifying a component for modification in a second manner.

4. The method of claim 3, wherein the step of identifying one or more suitable components comprises prioritising a predetermined number of components suitable for modification, the step of prioritising further comprising accessing financial data relating to the proposed modification.

5. The method of claim 3, further comprising, modifying at least one of the identified components in accordance with the identified manner.

6. The method of claim 5, further comprising upgrading components identified to be modified in a first manner and downgrading components identified to be modified by a second manner.

7. The method of claim 3, further comprising forwarding an indication of the components identified for modification to a change management system for the modifications to be performed.

8. The method of claim 1, wherein the collected data is collected from the computer infrastructure during operation of the service over a predetermined period.

9. An article comprising a non-transitory machine readable storage to store instructions that when executed by a processor-based system cause the processor-based system to:

obtain first service level objective compliance data for a selected service level objective for a computer infrastructure comprising a plurality of components, the compliance data being calculated using data collected from the computer infrastructure;

calculate second service level objective compliance data for the selected service level objective using in part the collected data and for a selected service level quality objective a value that meets that objective;

calculate a difference between the first and second data; and

identify, based on the calculated difference, one or more components suitable for modification.

10. The article of claim 9, wherein the quality level of the service is defined by a plurality of service level objectives, the storage medium storing instructions that when executed by the processor-based system cause the processor-based system to recalculate the second service level objective data for each service level quality objective of each service level objective.

11. The article of claim 9, wherein the collected data is collected from the computer infrastructure during operation of the service over a predetermined period.

12. A system comprising:

a service level objective analyser comprising a processor adapted to;

obtain first service level objective compliance data for a selected service level objective for a computer infrastructure comprising a plurality of components, the compliance data being calculated using data collected from the computer infrastructure;

calculate second service level objective compliance data for the selected service level objective using in part the collected data and for a selected service level quality objective a value that meets that objective;

calculate a difference between the first and second data;

identify, based on the calculated difference, one or more components suitable for modification; and

a scenario analyser comprising a processor adapted to determine how to change the computer infrastructure based on the identified one or more components.

13. The system of claim 12, wherein the collected data is collected from the computer infrastructure during operation of the service over a predetermined period.
